Hammer & Screwdriver Problem with ssh -n IP
I am able to login to server x from y in shell script. But after that command is get executed on server y. I need the command to be executed on server x.
Ex.

Code:
ssh -n 0.0.0.X
ls -ltr

Above script I am executing from 0.0.0.Y

I got result but it executed on server Y server. But when I use
Code:
ssh -n 0.0.0.X  ls -ltr

it works.

If you look at the man pages of ssh, this is how it is:

Code:
SYNOPSIS
     ssh [-1246AaCfgKkMNnqsTtVvXxY] [-b bind_address] [-c cipher_spec] [-D  [bind_address:]port] [-e escape_char] [-F configfile] [-i identity_file] [-L
         [bind_address:]port:host:hostport] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-R  [bind_address:]port:host:hostport] [-S ctl_path]
         [-w local_tun[:remote_tun]] [user@]hostname [command]

So, you see, ssh <option> [command] .. no wonder ls -ltr works on server X if it's on the same line.

Please use code tags as required by forum rules!

Why do you use the -n option?

Thanks for using code tags.

I repeat: Why do you use the -n option?

And, be aware that neither Cat nor Df will work.
